Abstract
Abstract A heat pipe comprising a flexible sealed envelope and an internal wick structure comprising two sets of cross-members in transverse relation to each other, the cross-members being transverse to the flexible axis of the envelope. The wick structure may be a cylindrical mesh screen consisting of orthogonal metal wires disposed within a cylindrical metal bellows such that each of the cross wires is at an angle with respect to the flexible axis of the bellows.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A heat pipe comprising: a. a flexible sealed envelope having a longitudinal axis; b. a wick structure within said envelope, comprising a plurality of first crossmembers in transverse relation to a plurality of second crossmembers, said first crossmembers and said second crossmembers each being transverse to said axis; and c. a working fluid saturating said wick structure within said envelope.
Claim 2
Dependent Claim
60 words
A heat pipe comprising: a. a flexible sealed envelope having a longitudinal axis; b. a wick structure within said envelope, comprising a plurality of first crossmembers in transverse relation to a plurality of second crossmembers, said first crossmembers and said second crossmembers each being transverse to said axis; and c. a working fluid saturating said wick structure within said envelope.
Claim 3
Dependent Claim
18 words
The heat pipe of claim 1, wherein said first crossmembers are in slidable relation to said second crossmembers.
Claim 4
Dependent Claim
16 words
The heat pipe of claim 1, wherein said first crossmembers are bonded to said second crossmembers.
Claim 5
Dependent Claim
31 words
The heat pipe of claim 1, wherein the angle between each of said first crossmembers and each of said second crossmembers is in the range from about 30* to about 150*.
Claim 6
Dependent Claim
75 words
A heat pipe comprising: a. a cylindrical flexible metal bellows; b. means sealing said bellows at the opposite ends thereof; c. a cylindrical wick structure within said bellows, comprising a plurality of first metal crossmembers in slidable transverse relation to a plurality of second metal crossmembers, said first crossmembers and said second crossmembers each being transverse to the longitudinal axis of said bellows; and d. a working fluid saturating said wick structure within said bellows.
Claim 7
Dependent Claim
75 words
A heat pipe comprising: a. a cylindrical flexible metal bellows; b. means sealing said bellows at the opposite ends thereof; c. a cylindrical wick structure within said bellows, comprising a plurality of first metal crossmembers in slidable transverse relation to a plurality of second metal crossmembers, said first crossmembers and said second crossmembers each being transverse to the longitudinal axis of said bellows; and d. a working fluid saturating said wick structure within said bellows.
Claim 8
Dependent Claim
